If you think optical image stabilization (OIS) is a gimmick that exists merely to allow manufacturers to hype up their latest smartphone camera, you need to watch this video. A simple demo put together by Samsung demonstrates exactly what OIS does and why it is actually quite useful in helping you take the best photos possible.

We slid in an iPhone 6 for comparison. It lacks OIS altogether (you need to pony up for the iPhone 6 Plus to get that feature). We’ll let the results speak for themselves.

For more on how the cameras of the Galaxy S6 and iPhone 6 stack up, see our full comparison post.
